The above ":verbose set" etc. will show you that it is not actually set to nine hundred and ninety-nine lines.

If, OTOH, what you want is a full-size Vim with empty split windows on
both sides of the current one, then it should also be possible, maybe
this way (untested, and to be put in gvimrc, or in a function called at
the GUIEnter event):

set lines=999 columns=999
if &columns > 90
left vertical new
wincmd w
right vertical new
wincmd W
set winwidth=90
wincmd =
setlocal winfixwidth
endif

":verbose set lines? columns?" (without the quotes of course) still
applies to find out what altered your gvim size. For the sizes of the
split-windows you could similarly ask

:verbose set wfw? wiw? wmw?


Best regards,
Tony.
